Demand of intelligent knowledge acquisition and processing methods is seen for the last decade. Virtual learning environments (VLE), as an educational business computerizing solutions, have analogous problems. Existing VLEs are rather primitive human-based empirical instruments. The paper is dedicated to intelligent knowledge acquisition in VLE. The drawbacks of empirical VLEs are emphasized. The paper describes modern e-learning mechanisms (methods), reveals main aspects of intelligent tutoring systems (ITSs). Control-view based knowledge acquisition method for ITS is proposed.
